Charlie McCann combines mechanical engineering expertise with practical home improvement guidance, specializing in the technical analysis of residential systems. With 18 years of experience in HVAC design and energy efficiency consulting, he translates complex technical specifications into actionable homeowner decisions.
Charlie's approach centers on systems thinking, analyzing how heating, cooling, insulation, and ventilation work together across different climate zones. His research-driven articles break down efficiency ratings (SEER, AFUE, HSPF), explain load calculations, and compare performance metrics so homeowners understand the "why" behind equipment recommendations.
As a certified energy auditor and building performance analyst, Charlie has evaluated thousands of homes across all DOE climate zones. He understands how regional factors like heating degree days, humidity levels, and local building codes affect system selection and long-term performance. His technical deep-dives help homeowners make informed decisions based on quantifiable data rather than sales pitches.
Charlie holds certifications from ASHRAE and the Building Performance Institute. He regularly collaborates with mechanical engineers, energy modelers, and specialized contractors to ensure his recommendations reflect current industry standards and emerging technologies.
